Abstract
How do geopolitical frictions matter for the diffusion of technology? Based on a guns-versus-butter model involving two countries (a technology leader and a technology laggard), we study the direct and indirect effects dual-use (or general-purpose) technology transfers on the countries’ payoffs and hence their preferences over such transfers. A central finding is that, when the initial technological distance between the two countries is large whereas the degree of output security is low and the laggard’s capacity to absorb state-of-the-art technologies is relatively limited, the leader has an incentive to block a transfer to the laggard. The analysis also unveils the possible emergence of a “low-technology trap.” Using data on cross-border patent flows as a proxy for technology transfers and sanctions as a proxy for conflict over the 1995–2018 period, we present evidence in support of the theory.
